# Time Vault Pools The most common question people ask is *where does the upfront yield come from?* Ultimately, Time Vaults use multiple methods of "Pools" to make upfront yield possible. Here are three of the current most used pool types that enable upfront yield. * Yield Pools * Liquidity Pools * Boost Pools ### Example #1: Yield Pool *How it works:* * When Time Vault begins generating yield from it's yield source (Aave, Lido, etc), the yield is redirected into a "Yield Pool" * The only way to get the yield out of the Yield Pool is by burning TBTs * The amount of yield you can withdraw from Yield Pool is proportional to a user's ownership of TBTs * For example: If a user owns 10% of all TBTs from this Time Vault, they have the rights to burn and redeem 10% of all yield in this Yield Pool *Overview:* * Available Yield: Generated from previous stakers principal * Yield Claim: Burn TBTs * Pro: Creates perpetual available yield source * Con: Takes time to jumpstart and accumulate. ### Example #2: Liquidity Pool *How it works:* * Individuals can add liquidity to TBT tokens * For example: ETH/TBT * When a user mints TBTs from a Flashstake, the TBT tokens are sold into this Liquidity Pool. * In this model, LPs are providing this upfront yield so they can earn trading and potentially liquidity mining fees. *Overview:* * Available Yield: Generated from TBT liquidity providers * Yield Claim: Swap TBTs * Pro: Creates liquidity for TBTs * Con: Must attract LPs ### Example #3: Boost Pool *How it works:* * Anyone can deposits money directly into a Boost Pool * For example: Blockzero Labs deposits $1000 USDC into the Aave v3 Time Vault * When a user mints TBTs from a Flashstake, the TBT tokens are burned to redeem USDC from the Boost Pool * In this model, anyone can subsidize the cost to jumpstart a Time Vault *Overview:* * Available Yield: Donated by person or entity * Yield Claim: Burn TBTs * Pro: Easy to start * Con: Donation is an expense --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
